SPECIFICATION forming part of Letters Patent No. 767,230, dated August9, 1904.

Application filed March 29, 1904. Serial No. 200,545. (No model-1 To all1071/0771/ it 77u07/ concern:

Be it lgnown that I, ABNER VILsoN HORN- BERGER, a citizen of the UnitedStates, residing at Milton,-in the county or' Northumberland and Stateot' Pennsylvania, have invented new and useful Improvements inlNrenches, or' which the following is a speciiication.

My invention relates to improvements in wrenches, and which, althoughapplicable as in the ordinary use of wrenches for`turning a nut, is alsoequally effective-as, for instance, where this would not otherwise bepossible because oi' the lack of space or presence of obstructions tothe required manipulation or actuation of the wrench.

It is the object of the invention to provide such improvements as willenable the jaw to be moved irrespective of the handle, so that the nutmay be securely engaged and the jaw then held in its engaged positionwhile the handle is moved to turn up and tighten the nut or loosen thesame.

To these ends the invention consists in the various constructions andcombination of parts, the peculiarities and distinguishing characters ofwhich when applied to a wrench will be hereinafter more specificallydescribed.

Referring to the accompanying drawings, which form a part ot' thisspecification, Figure l is a side elevation showing how the wrench isheld and operated by the hand ot" the user. Fig. 2 is a longitudinalsectional view showing how the parts cooperate with eachother in use.Figs. 3 to 6, inclusive, show the parts in diiferent positions.

In the drawings, l designates the handle, which may be ot' any suitableform and size and which is slotted at its upper end, so that thelthumb-piece 2 may be pivoted therein at' its lower end and so, also,that jaw 3 may be pivoted in the upper end, with thecentral part of theratchet slide-piece or dog 4 operating in the slot between theratchet-teeth 6 on the lower side of the jaw 3 and the upper end of thethumb-actuated piece or detent 2, said dog having lateral guide-flanges4u at its ends contacting or engaging with opposite surfaces or edges ofthe handle l to hold said dog as against endwise displacement.

The lower side or edge of the nut-engaging jaw 3 is constructed on theare of a circle, and

the lower edge or side thereof has ratchetteeth 6 formed' thereon, andthe adjacent upper edge oi' the slide has corresponding teeth 7 made onsaid part, while a tooth or teeth 3 are formed on the inner upper cornerof the pivoted thumb-piece 2 and adapted to engage a notch 9, formed inthe projecting end of the ratchet slide-piece 4.

The pin l0, pivoting the nut-engaging jaw 3 in the slot in the upper endof the handle, may be a screw, with its head countersunl in one side andscrewed into the other, as shown, and the pivot-hole maybe somewhatlarger than the pin to allow the jaw 3 to move freely about on its pin.

Then it is desired to use the device as a straight wrench, the partswill be adjusted as shown in Figs. l and 2, when the 3teeth of thesliding piece will engage the ratchet-teeth on the lower edge of the jawand the thumb-piece below will hold the parts in position.

Then it is wished to turn the jaw to one side at a slight angle to thehandle after the jaw is engaged with the nut, the teeth of theslide-piece will be engaged with those of the jaw, and the tooth 3 ofthe thumb-piece may be engaged with the notch 9, formed on theprojecting end of the'slide-piece,and the latter held in place by slightpressure on the thumbpiece, as shown in Fig. 3, or the thumb-piece maybe drawn down out of the way altogether, so that the jaw may extend at aright angle to the handle, as seen at Fig. 4. Vhen it is desired to turnthe jaw in the opposite direction at a partial angle to the handle, thejawholding slide-piece may hold the jaw locked in place by thethumb-piece, as shown in Fig. 5, or the thumb-piece may be drawn down,with its tooth 3 out of engagement with the notch in the ratchet-slide,and the jaw 3 will then extend at a right angle and the Wrench sooperated, as shown in Fig'. 6.

A larger or smaller jaw may be pivoted on the handle, as will be readilyunderstood.

It will also be understood that other changes and arrangements may bemade with my invention without departing from the nature or spiritthereof.

That l claim as my invention is- 1. A wrench having an axially-movablejaw, a slide or dog adapted to engage said jaw, and

IOO

all

an axially-movable detent'adapted to engage l teeth or notch es, and adetent also pivoted in said slide either endwise or laterally.

2. A wrench having an axially-movable Jaw,

a slide or dog adapted to eng'age said jaw, and

an axially-movable detent adapted to engag'e said slide diagonally,endwise or laterally.

3. A wrench having' an axiallyanovable jaw, a slide or dog', said jawand dog having intermeshing' ratchet-surfaces.and a detent adapted toengage said slide or dog' diagonally, end- Wise or laterally.

4. A Wrench having' a pivoted nut or object engaging' jaw, a slidingdog', said jaw and dog having' intergeared ratchet teeth or notches, anda detent having a tooth at a corner edge engaging and holding said dog nposition.

A Wrench having a pivoted nut or object engaging jaw, having' a notchedor ratchet surface, a sliding dog' having a corresponding surfaceengaging' the ratchet-surface of said jaw, and a notch at its rearcorner edge, and a detent having a tooth at a corresponding edgeengaging said notch.

6. A Wrench having a single handle, a nut or object engaging jaw pivotedin one end of said handle, a sliding' dog also arranged in the latterand having a notch in its corner edge, said jaw and dog havingintergeared ratchet said handle and having at a corner edg'c a toothengaging said notch.

7. A Wrench having' a handle. a nut or ohject engaging' jaw centrallypivoted in one end of said handle, a dog arranged to slide in saidhandle and having' lateral guide-fianges eng'aging the opposite edg'esof said handle, said jaw and dog having intergeared ratchet-surfaces,and a detent also pivoted in said handle and having' a tooth engaging' anotch in a corner edge of said dog'.

8. A Wrench having a handle provided With a centrallypivoted nut orobject engaging jaw, a sliding dog having lateral guide-flanges,engaging the opposite edges of said handle, and a notch in a corner edgethereof, said jaw and dog having intergeared ratchet-surfaces, and adetent pivoted in said handle and having at a corner edge a toothengaging said notch, also a thumb or finger piece.

In testimony whereof I have signed rny name to this specification in thepresence of two suhscribing, Witnesses.
